Embodiment Construction

[0021] In order to solve the technical problem of frequent replacement of dust-removing bags in the prior art, the present invention provides a back-blowing and dust-removing method for TRT dry-type dust-removing system, which has good dust-removing effect and can effectively prolong the service life of the dust-removing bag. The back blowing dedusting method comprises the following steps,

[0022] a. To set up the dust removal system, at least five bag dust collectors equipped with filter control devices and back blowing control devices are connected in parallel to the gas output end of the back blower, and the signals of the back blower and the bag filter are controlled Line, connected with the control module of the automatic control mechanism to form a TRT dry bag dust removal system;

[0023] b. Blast furnace gas collection and dedusting. Blast furnace gas is collected by gas collecting pipes and then distributed into each bag filter, and passes through the filter bags set...

Abstract

The invention discloses a blowback dust removal method for a TRT dry dust removal system, belongs to the technical field of design and manufacture of metallurgical environment-friendly dust removal equipment. The blowback dust removal method for the TRT dry dust removal system has a good dust removal effect and is capable of effectively prolonging the service life of a discharge bag. By virtue of the blowback dust removal method, in the process of blowback dust removal, the discharge bag is blown back once each time, and blowback dedusting is completed by virtue of repeated delayed operation.

Description

technical field [0001] The invention relates to a back blowing dust removal method, in particular to a back blow dust removal method used in a TRT dry dust removal system, and belongs to the technical field of design and manufacture of metallurgical environmental protection dust removal equipment. Background technique [0002] The TRT process can be divided into dry and wet. The process of using water to reduce the gas temperature and dust removal and setting the TRT device is called the wet TRT process, while the process of using dry dust removal, that is, bag or electric dust removal and setting the TRT device is called the dry type. TRT process. Dry dedusting and TRT process is the best solution to save energy and reduce energy consumption of blast furnace. It can not only make full use of the secondary energy of the blast furnace, but also save a large amount of industrial water, correspondingly reduce the secondary power consumption, and also reduce environmental pollu...
